Yet more rumours regarding what Sony will/won't say at today's supposed PS4 unveiling have appeared, with sources claiming the machine will launch in two separate hardware versions for around £280 and £340.

The report, which comes via US aggregator Kotaku, says two units priced in local money at $429 and $529 will be available at launch this November, presumably offering different hard drive capacities and maybe more incentives, with the source also claiming a dedicated PS4 app will let users buy and manage games from a phone or tablet -- and there will be an Xbox Live-like subscription fee to access most of the online options.
